[uremia/3 Ernst Breitling and Julius Patzelt By q ww that 14mm Patented Mar. 30, 1937 UNITED STATES PATENT OFFICE CASH REGISTER, ACCOUNTING AND THE LIKE MACHINE Application September 5, 1935, Serial No. 39,209 In Germany November 7, 1934 6 Claims.

The invention relates to a cash register, accounting and the like machine and more particularly to a differential device consisting of two complementarily moved members for such ma- 5 chines, provided with several totalizer rows for adding and total operations and having means for recording such operations. Such a differential device is shown and described in Letters Patent of the United States, No. 2,039,143, issued to 10 Ernst Breitling on April 28, 1936.

The main object of the invention is to warrant an equal total movement in each operation of the complementarily moved differential members, by arranging novel actuating means for said members.

Another object of the invention is to provide a minimum movement device for the registering means set by the differential device as indicating and printing means by which they are set directly from the one figure to the other without having passed zero in each operation.

Another object of the invention is to adapt the totalizer engaging means for simultaneous engagement of any one, or several, or all totalizer 5 rows, at will.

Another object of the invention is to adapt one totalizer of any row for itemizing operations and control its engagement in addition to one or several other totalizer rows during such operations.

Another object of the invention is to arrange a main totalizer and preferably with the itemizing totalizer in the same row and to control the simultaneous engagement of the main totalizer in addition to any or several totalizer rows.

Another object of the invention is to provide disabling means for the main totalizer engaging means in multiple item total taking operations for changing the timing of such engagement.

A still further object of the invention is to provide a novel arrangement for selecting a totalizer row and any totalizer in said row.

Another object of the invention is to reduce the number of revolutions of the main shaft and do away with idle machine operations in total taking operations.

Another object is to adapt controlling means for the totalizer engaging means actuated in adding operations by the machine drive and in total taking operations by the machine operation conditioning means in cooperation with the totalizer selecting means.

Another object of the invention is to enable transfer of a total taken from a totalizer to another totalizer of the same row during a single 55 machine operation.

Further objects of the invention will be pointed out in the following detailed description with reference to the annexed drawings.

A preferred form of an embodiment of the invention is shown in the annexed drawings.

K ey board The key board of a machine embodying the invention by way of example, contains, in addition to several rows of amount key banks l0 (Fig. 1), three rows of totalizer selecting, or special keys ll, 12 and [3, of which the keys II are adapted to select clerk totalizers, the keys I2 department totalizers, and the keys I3 transaction totalizers. For adding operations one key in each one of these three banks of special keys can be depressed simultaneously. Further, a multiple item key id is arranged in a fourth key bank, which key has to be depressed for entering a series of multiple items. A motor key 15 of the same bank serves to release the machine for all adding and item total taking operations. For taking totals from the remaining totalizers, the machine release is effected by means of a setting lever it set to total taking, which in its adding position normally is locked by a lock H. To condition the machine for the different modes of operation, a mode of operation or machine conditioning lever 98 is provided which can be set by the sales person either to adding position for entering amounts, or to the T position for taking a multiple item total. The remaining positions, X, Z, GX, GZ of the conditioning lever is provided for taking sub-totals or totals from the special totalizers and the main totalizer respectively, are, normally, locked and can be used only by the authorized persons after inserting keys in looks it].

Amount difierential devices The amount differential devices of the machine (Fig. 13) consist of a main differential member 26 and an auxiliary dilferential member H in each denominational order, both of which members are rotatably arranged on a shaft 22. A link 23 is linked to the main differential member 20, and a link 2 to the auxiliary differential member 2!. The free ends of the two links 23 and 24 are hinged together by a stud which carries a roll r 25 guided in a curved groove 26 of an actuating arm 21'. The actuating arms 2? of all denominational orders are mounted upon a shaft 28, which shaft at each machine operation is rocked through a certain angle, first clockwise, and then counter-clockwise. This is effected by a double-armed lever H5, which is mounted upon the shaft 28 and provided with rollers on its actuated by a double cam disk 215 of a drive shaft 2i? performing during a machine operation a revolution in clockwise direction. In consequence of the clockwise rocking movement of the arm 21 the differential members 28 and 2! are moved one against the other and closed like the tongues of scissors or pliers. When the one of the two differential members engages the foot of an amount key ill at the time depressed and is thus arrested, the other differential member actuated by the arm 2'! continues its movement till it contacts from the other side the foot of the respective amount key. Corresponding to the value of the key depressed, the two differential members and 2| are rocked different degrees. The roller 25 will occupy, according to the key just depressed, different positions in the curved groove 28 of the actuating arm 27. The total of the respective movements of the two differential members and 2!, however, is the same each time. In order to secure the equal total movement in all operations, at the end of the clockwise movement of the arm 27 the curved groove 25 is positioned concentrically to the shaft 22 (see Fig. 15). Upon the return movement, which takes place after an interruption of a certain duration of the actuating 2?, the members 2%, 2i are moved apart, and they are arrested in the zero position by a rigid stop 29 (Fig. 13). A setting member 38 is rotatably arranged on the shaft 22, a pin 3! of which projects into the path of the differential members 28 and 2! and is gripped by aovaese them in a scissors-like manner, and thereby it is immediately moved from its former position into its new one corresponding to the depressed amount key. The setting member 30 is connected by a gear 32 arranged on a shaft 31, with the appertaining type wheel and the indicating wheel, so that these are set according to the amount key depressed.

A detent 33 adapted to be moved upwardly by depressing an amount key if), is arranged in each amount key bank. An extension of a zero stop pawl 35 rockably mounted upon a fixed stud 36, which normally is in the path of a shoulder 20a of the main differential member 20 holding it in zero position, engages a pin 34 of the detent 33. When the detent 33 is moved upwardly by depressing an amount key, the pin 34 rocks the Zero stop pawl 35 into inoperative position, whereby the main differential member 20 is released to be moved in accordance with the value of the key depressed. Teeth 20b of the differential member 26 mesh with a gear 38 mounted upon a shaft 39, with which gear the intermediate pinions ll] allotted to one single row of totalizers each, are in engagement. Thus, all four intermediate pinions 413 of each denominational order, upon setting of the main differential members 25], are set to the value of the depressed keys and rotated backwardly by the same value upon the resetting of the differential members. For amount entering, the selected totalizer is engaged, in a manner to be described hereinafter, with the intermediate pinions 4-D before the start of the resetting movement of the differential members 20.

Totalieer selection To select one of the totalizers the following arrangement has been provided. At this point of the description, only the selection of the three rows of special totalizers which are under control of the keys ii, l2, and 13 will be considered.

A differential device similar to the amount differential device consisting of a main differential member 41 and an auxiliary differential member t2 both of which are rotatably arranged on the shaft 22 is allotted (Fig. 4) to each of the three special key banks l I, I2 and I3. A link 43 pivoted to the differential member 4!, and a link 44 pivoted to the auxiliary differential member 42 are hinged by a stud mounted at their free ends and provided with a roller 45 guided by a bent over flange 36 of an actuating arm 41 under the action of a spring 48, acting upon the differential device. The actuating arms 4! are loosely mounted upon a shaft 28 the axis of which is the same as the axis of the shaft 28. A bail engages the lower edges of the three actuating arms 41 of the special differential devices. This bail 55 is secured to an arm 55 (Fig. 2), the roller 51 of which is guided by a curved groove 58a of a cam disk 53 performing one revolution at each machine operation. A detent 6! appertaining to each special key bank (Fig. 4) is moved upwardly by pressing a totalizer selecting or special key, and the Zero stop pawl 52 is rocked by a pin 6| of the detent 69 out of its operative position. During the following machine operation, the arm 56 (Fig. 2) is rocked clockwise by the curved groove 53a and the bail 55 connected to the arm 56, carries along (Fig. 4) the actuating arms 41. The arched flange 46 forces the roller 45 towards the shaft 22, whereby the two differential members 4| and 42 are rotated in opposite direction, till they embrace the foot of the depressed key from two
